im not a ford guy so im a lil lost with this install i just did, the supercharger is installed and everything is running but its having a lot of detonation/backfire. the kit is a procharger psc1 with the 7 psi pulley however the injectors i have are 42 lbs and the fuel pump is 255, i have not installed either yet bc im wondering if its running to lean or rich currently, the ECM chip has been installed that came with the kit, i have the air fuel guage currently spliced in to the black wire on the O2 and its reading rich but i know detonation is usually linked to leaness. can any one tell me if i have the air fuel on the wrong wire or if the injectors and stuff will help me out?

Did you get the computer dyno tuned?

yes the ECM chip is pretuned to run with the 7lbs pulley with that exact charger.
